Seahorses.

Seahorses are amazing creatures. They live in shallow tropical waters. They are related to pipefish and vary in size from 0.6 in to 14 in. They use their elongated snout to feed. Their diet consists of plankton and very small crustaceans that float in the water. These fish are unique because they mate for life and the males carry the eggs until fertilization.

Swell Shark!

Photocredit   To learn more
This is the swell shark they are carnivore creatures that dwell on the rocky seafloor of the pacific ocean. When threatened these guys will make an u shape of its body then swallow sea water to make itself look twice as big scaring off threats. In day they are usually harmless little creatures staying camouflaged on rocks. By night they dwell and eat fish or stay still with its mouth open for a fish to swim in. Sharks are cartilages which mean it has no bones which make these guys pretty flexible. These sharks lay leathery eggs that are causally mermaid purses. Depending on water temp. they could hatch in nine to twelve months.

Flounder

All five flounder species are very similar in appearance but can vary quite dramatically in size. Flounder can vary from 5 to 25 inches in size depending on the species, but all flounder species have a rounded, flattened body shape with a medium-sized flat tail fin.

Frilled Shark CNN Video

Check out this ancient shark recently caught off the coast of Australia! It is a "living fossil," an organism that has remained virtually unchanged throughout the fossil record. We will talk more about living fossils in class soon.

Blobfish

Blobfish live at depths between 600–1,200 m (2,000–3,900 ft) where the pressure is several dozen times higher than at sea level, which would likely make gas bladders inefficient for maintaining buoyancy. Instead, the flesh of the blobfish is primarily a gelatinous mass with a density slightly less than water; this allows the fish to float above the sea floor without expending energy on swimming. Its relative lack of muscle is not a disadvantage as it primarily swallows edible matter that floats in front of it. Blobfish eat invertebrates like crabs and sea pens.
